AbstractDuring 2004 and 2005 measurements of mesospheric/lower thermospheric (80–100km) winds have been carried out in Germany using three different ground-based systems, namely a meteor radar (36.2MHz) at the Collm Observatory (51.3°N, 13°E), a MF radar (3.18MHz) at Juliusruh (54.6°N, 13.4°E) and the LF D1 measurements using a transmitter (177kHz) at Zehlendorf near Berlin and receivers at Collm with the reflection point at 52.1°N, 13.2°E. This provides the possibility of comparing the results of different radar systems in nearly the same measuring volume. Meteor radar winds are generally stronger than the winds observed by MF and especially by LF radars. This difference is small near 80km but increases with height. The difference between meteor radar and medium frequency radar winds is larger during winter than during summer, which might indicate an indirect influence of gravity waves on spaced antenna measurements.
